Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ventilation technology, and in particular relates to a rainproof ventilation grille. Background Technology
[0002] Grilles are commonly used at ventilation openings in buildings, vehicles, tunnels, and other locations to improve air quality. Existing grille structures typically consist of an outer frame for mounting on the ventilation opening and multiple spaced grille panels within the frame. These panels are usually angled to achieve both ventilation and rain protection. With this structure, most rainwater is intercepted by the angled surface of the grille panels and then flows down and is discharged, preventing rainwater from directly entering the room. However, in strong winds, water droplets mixed with the wind, especially small ones, are difficult to trap by impacting the grille panels and can still be blown into the room, resulting in poor rain protection and ineffective prevention of rain intrusion. In some structural designs, to improve rain protection, the angle of the grille panels is adjusted, or even the gaps between the panels are closed. However, this approach sacrifices ventilation, is complex to adjust, and cannot simultaneously achieve both ventilation and rain protection. Utility Model Content
[0003] In view of this, in order to solve the above-mentioned technical problems, this utility model proposes a rainproof and ventilated grille with a simple structure that combines rainproof and ventilation functions and effectively intercepts rainwater mixed in the wind.
[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0005] A rainproof and ventilated grille, characterized in that: it includes a grille frame, a plurality of equally spaced parallel grille plates installed within the grille frame, an upper sealing plate located at the top inner side of the grille frame, and a lower sealing plate located at the bottom inner side of the grille frame; the top of the uppermost grille plate is connected to the bottom of the upper sealing plate, and the bottom of the lowermost grille plate is connected to the top of the lower sealing plate; each grille plate includes an inclined plate, an upper baffle located at the top of the inclined plate, a lower baffle located at the bottom of the inclined plate, and a wire mesh layer located on the back of the inclined plate; the upper baffle of the lower grille plate is positioned higher than the lower baffle of the adjacent upper grille plate.
[0006] The grid frame is installed at the ventilation opening; the upper sealing plate prevents rainwater from entering through the gap between the grid frame and the uppermost grid plate, and the lower sealing plate prevents rainwater from entering through the gap between the grid frame and the lowermost grid plate; the upper baffle of the lower grid plate is positioned higher than the lower baffle of the adjacent upper grid plate to prevent wind and rain from directly entering; a wire mesh layer is set on the back of the inclined plate. Rainwater carried in by the wind will hit the wire mesh layer. Compared with directly hitting the inclined plate, the wire mesh layer has a good gas-liquid separation effect. Small raindrops mixed in the wind are intercepted by the wire mesh layer, and after being collected into large water droplets in the wire mesh layer, they drip onto the inclined plate of the lower grid plate and flow out along the inclined plate.
[0007] Furthermore, the upper baffle includes a vertical section and a bent section; the bottom of the vertical section is integrally connected to the top of the inclined plate; the bent section is formed by extending forward and upward from the top of the vertical section, then extending vertically upward again, and then bending backward and upward.
[0008] The upper baffle uses a structure with vertical sections and bent sections, which can effectively intercept rainwater.
[0009] Furthermore, the lower baffle is a vertical plate structure, which has the function of intercepting rainwater and guiding the flow.
[0010] Furthermore, the wire mesh layer is detachably connected to the inclined plate; the wire mesh layer includes a mounting frame and a wire mesh disposed within the mounting frame.
[0011] Furthermore, a slot is provided at the bottom of the mounting frame or the bottom of the wire mesh; an insert block adapted to the slot is provided on the back of the inclined plate; the wire mesh layer and the inclined plate are detachably connected by interlocking the slot and the insert block.
[0012] The wire mesh layer and the inclined plate are detachably connected, which facilitates later cleaning and maintenance; the connection method of slots and plugs makes disassembly and assembly convenient.
[0013] Furthermore, the mounting frame is provided with a vertically downward guide plate at its lowest position; the guide plate is suspended above the inclined plate of the adjacent lower layer.
[0014] The deflector is used to smoothly guide the rainwater separated from the wire mesh layer to the lower inclined plate for discharge.
[0015] Compared with the prior art, the rainproof ventilation grille of this utility model has the following advantages:
[0016] (1) The rainproof ventilation grille of this utility model has a simple structure. Through reasonable structural design and setting a wire mesh layer on the grille plate, it can improve the interception rate of rainwater mixed in the wind, optimize the vapor-water separation effect, effectively prevent rainwater intrusion, and not affect the ventilation effect.
[0017] (2) The wire mesh layer in the rainproof ventilation grille of this utility model adopts a detachable connection method, which is convenient for later cleaning and maintenance and easy to disassemble and assemble. Attached Figure Description
